Definitions

  • the suction phenomenon is due to the mass of the needle which gradually leaves the implanted chamber and the bent shape of the Huber needle which tends to artificially increase the volume of said chamber.
  • the action device would then normally react to empty the bag in the tubing. It could be the own deformation of said pocket induced by its filling ⁇ 1a, 1b Figure 1 ⁇
  • This pin would have a shape such an open “U” ⁇ 2a Figure 2 ⁇ or a "V" ⁇ 2b Figure 2 ⁇ for example whose shape would correspond to an opening larger than the opening of the pocket
  • a device whose device consists of a device of a shape such as a "U" ⁇ 2a Figure 2 ⁇ or a "V" ⁇ 2b Figure 2 ⁇ ptaced inside ⁇ 2c Figure 2 ⁇ , tightening during filling of the reservoir ⁇ 2c, Figure 2 ⁇ ... ⁇ and whose mechanical force allows to provoke the emptying the tank by flattening it ⁇ 2e Figure 2 ⁇ when opening the connection tap to the chemotherapy needle connection tubing
  • a device whose device consists of a device of a shape such as a "U" ⁇ 2a Figure 2 ⁇ or a "V" ⁇ 2b Figure 2 ⁇ placed outside the tank ⁇ 2d Figure 2 ⁇ , tightening while filling the tank ⁇ 2d Figure 2 ⁇ ... ⁇ and whose mechanical force makes it possible to cause the tank to be emptied by flattening it ⁇ 2e Figure 2 ⁇ when opening the connection tap to the chemotherapy needle connection tubing
  • An expansion device such as a spirally wound spring placed on the outside of the pocket which after being deformed during filling, ⁇ 4a Figure 4 ⁇ would drain the pocket by returning to its original position ⁇ 4b Figure 4 ⁇ when opening this duct after connection to the drain pipe.
  • An expansion device such as a spirally wound spring placed inside the pocket which after being deformed during filling, ⁇ 4c Figure 4 ⁇ would drain the pocket by returning to its original position ⁇ 4d Figure 4 ⁇ when opening this duct after connection to the drain pipe.
  • An expansion device such as a succession of cerclips connected to each other or not, which would be forced to open when filling the device ⁇ 5a figure5 ⁇ to close again when opening the duct after connection to the drain pipe ⁇ 5b Figure 5 ⁇
  • a device of successive hemi circles such as a succession of cerclips connected or not between them placed outside the tank. figure5 ⁇ , but whose deformation will allow the reservoir to fill by the release of the constraint of said device ⁇ 5a figure5 ⁇ but which will return to its initial form tightened ⁇ 5b figure5 ⁇ after opening the connection tap to the chemotherapy needle connection tubing
  • a device that will, during its manufacture, made integral with a flat external device, such as a duckbill, figure6 ⁇ to inflict flattening ⁇ 6a figure6 ⁇ while allowing it to resume its original form of bladder during its filling ⁇ 6b figure6 ⁇ ; this progressive flattening thus causing the device to be drained into the tubing for connection to the chemotherapy needle.
  • a flat external device such as a duckbill, figure6 ⁇
  • a device that will be, during its manufacture, made integral with a flat internal device, such as a duckbill, figure6 ⁇ to inflict flattening ⁇ 6c figure6 ⁇ while allowing it to resume its original form of bladder during its filling ⁇ 6d figure6 ⁇ ; this progressive flattening thus causing the device to be drained into the tubing for connection to the chemotherapy needle.
